Localization
Beginning with SOS 5.0, the iPad is localizable to languages supported by Apple. Translations of dataset names and descriptions, Major Categories and Sub Categories, Keywords used for searching, and the iPad user interface buttons, labels, and popup text are all supported. A separate document, the Translations Manual, describes all aspects of creating these translations, which are created entirely on the SOS computer.
To set up localization on your iOS device, tap SettingsGeneralLanguage & Region. Then choose the desired Region first, followed by the Language. Below are examples for an iPhone. The iPad controls are very similar.

Selecting the region in iOS (screenshots are from an iPhone, but the process is similar on an iPad).

Selecting the language in iOS (screenshots are from an iPhone, but the process is similar on an iPad).
The iPad interface now uses the new language and country.
When you run the SOS Remote app, if there are translations available for the Data Catalog content or the iPad user interface controls, these will be automatically read from the SOS computer and used on the iPad app. If there are no translations available for that language, the default English text is used and if only some of the datasets have been translated, the interface will display a mix of datasets in that language and in English.
Note that if you have previously run the SOS Remote App and then change the Language and Region settings, you will need to remove the SOS Remote App from memory to reset it to use the new language. This is done by double-clicking the home button and swiping up on any SOS Remote app screens that appear.
The set of filters available in the Data Catalog include an extra filter that is available only on localized devices (the 4th one). It is used to display only those datasets that have names and descriptions translated to the localized language.

This example shows the set of filters when localized to Spanish in Mexico (with translations generated by Google Translate).

This example shows datasets that match the same filter when localized to Traditional Chinese in Taiwan.
